Sneaky customization in screenshot?

Uhhh...how does the person in this screenshot have costume gear mixed and matched with other gear, I know for a fact that the lincoln black costume pieces DO NOT appear in the regular menus. But in this screenshot we have grunge helmet, zipped mouth scarf, LB costume chest piece, military costume back pack, bright yellow gloves with black, grunge pants and victory yama boots!? I need an explanation ASAP, as I have been wanting this kind of customization since the beginning.
